『現場一発！単位職人』Magic Calculator

A one-click solution to your on-site unit problems.

Are you struggling with unit conversions at construction, civil engineering, or real estate sites?

"How many tsubo are in 50 square meters?"
"Exactly how many millimeters are in 1 ken?"
"I want to convert to liters to calculate the unit price per cubic meter."

Japanese construction sites use a mixture of unique units, including not only the metric system but also the shakkanho system.
"On-site One-Shot! Unit Master Magic Calculator" is a unit conversion app specifically designed for such professionals.

[Key Features]

1. Comprehensive coverage of all units needed on-site.

Simply switch between three tabs to support any unit.

Area: Square meters (m2) ⇔ Tsubo ⇔ Tatami (Edo-ma) ⇔ Are (a) ⇔ Tan ⇔ Acre
Length: Millimeters (mm) ⇔ Centimeters (cm) ⇔ Meters (m) ⇔ Sun ⇔ Shaku ⇔ Ken
Volume: Cubic meters (m3) ⇔ CC ⇔ Milliliters (ml) ⇔ Liters (L)

There's no "Convert" button. The instant you enter a value, the calculation results are updated in real time to all other units. It won't slow down your busy worksite.

We've also prioritized visibility by eliminating unnecessary decorations and making the font size as large as possible.
